"My back feels great," he told reporters on a conference call Tuesday to promote the Northwestern Mutual World Challenge, a tournament Dec. 5-8 at Sherwood Country Club in Thousand Oaks that benefits Woods' charities.

Woods, 37, fought lingering back pain while helping the U.S. team secure the Presidents Cup victory in Dublin, Ohio, nine days ago.

But since then, "I took a week off, I've trained this week, I've gotten a bunch of treatment" that eased the problem, Woods said.

The world's top-ranked player plans two more tournaments this year: One in Turkey on Nov. 7-11 and then his charity event, which pays $1 million to the winner.
